Point and shoot vs dslr.going on holiday?

I'm going on a holiday to scotland and I was wondering which camera to take. I have a Nikon D90, and a 50mm 1.4 lens which i originally bought for portrait photography. I don't have any other good lens apart from the one that came with the camera. I also have a point and shoot. Canon powershot sx220. Which to take?

Well if you want to end up with good technical quality, of course the answer is obvious - the 90.
You can take the 50 with you but I wouldn't recommend trying to shoot everything with it because it's tight - no wide shots.

If your point and shoot takes pictures you like normally, I'd take that one so you aren't lugging around a big, heavy camera for quick vacation shots. Vacations are usually fast moving, active times and the dslr seems like a one purpose camera for you, so enjoy the vacation with the small camera.

Depends on how hardcore you are. The D90's kit lens is one of the best out there, as is the 50mm.

When I went to Snowdonia earlier this year, I took a 5D, 17-40, 50mm, 135mm, 400mm, Mamiya RB67, 50mm Sekor and 90mm Sekor C, two film backs, a tripod, light meter, cable releases, filters. I assume that you'll be going by car, so I'll say you can never back enough, you can always decide what you want to use on the day and leave the stuff you don't need in the boot.

If you want to take photographs of the sights instead of snapshots you will want to take the Nikon. You might consider looking into an inexpensive zoom lens for flexibility in your travel photography.

Personally, I would take them both. The point and shoot would be a good camera to take out for a night on the town when you are visiting the pub or restaurant and do not want to have to manage a larger body and lens.

Both

For the snapshot moments use the powershot. But if you are looking out over the hilly and rough country. With the green patches and little roads.use the all might kitlens get wide put it in something like F11 [don't fear to use a little higher ISO if needed] and make that perfect shot.

Really a DSLR only shines if you take it with you and Scotland has allot of good looks to offer, the kitlens though obviously not super is more then able to give pretty good results. So for those real vista's and the play with the clouds, the air and the ground. Here a little preview

And I had a 28-75 lens with me so your kitlens can go wider. Think about that isn't that worth using a DSLR?

So take both.
